Can't confirm the latter but the former: gum over cyanotype has never
worked for me either. The idea is tempting though: let cy take care of
the delicate highlight rendering and print the shadows with gum. But I
invariably found that the dichromate nibbles away exactly the cy highlights
leaving only the shadows that I want to overprint anyway. If it is just
for the colour of cy one is much better served with one or more layers of
Prussian/Parisian Blue. Other solution: first print the gum layers,
finally print cy.
